If the West were trying to destabilize India I suspect it would be incredibly easy to achieve, which is exactly why there is that defensiveness and hitting at shadows. But the West isn't because India has long been a useful counter to regional powers.
What is absolutely true is that the Modi government is spectacularly corrupt. Every opponent of Modi is a "terrorist" -- even opponents in government. The government is falling further and further down the well towards fascism, all while proud Indians convince themselves that everyone else is actually the problem.
